-
This is a CSV Parser library which will help you to parse a selected CSV File in your Angular Application. Currently working with Angular version 16.x.x+ as tested along with backward compatibility with previous Angular versions.
-
This library is in compliance to RFC 4180
-
A simple Example can be found under src/app directory of this repository.
-
Simply run
npm iand then run the application using your preffered command.
npm i ngx-csv-parser
import { NgxCsvParserModule } from 'ngx-csv-parser;
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { NgxCsvParserModule } from 'ngx-csv-parser';
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
NgxCsvParserModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }- Patreon Tofiq Quadri ✔
-
The library has 2 configuration options.
-
header: true or false. This will allow you to make the first row of your CSV file act as the key for the result and the data from the remaining file as the value for those objects.
-
Example if the csv data is:
-
firstName,lastName
-
John,Doe
-
In case the header config is true the result will be:
[
{
firstName: 'John',
lastName: 'Doe'
}
]- In case header config is false the result will be:
[
['firstName', 'lastName'],
['John', 'Doe']
]- delimiter: the marking factor which decides which symbol should be used to split the file.
- Default delimiter is:
','
import { Component } from '@angular/core';
import { ViewChild } from '@angular/core';
import { NgxCsvParser } from 'ngx-csv-parser';
import { NgxCSVParserError } from 'ngx-csv-parser';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent {
csvRecords: any[] = [];
header = false;
constructor(private ngxCsvParser: NgxCsvParser) {
}
@ViewChild('fileImportInput', { static: false }) fileImportInput: any;
// Your applications input change listener for the CSV File
fileChangeListener($event: any): void {
// Select the files from the event
const files = $event.srcElement.files;
// Parse the file you want to select for the operation along with the configuration
this.ngxCsvParser.parse(files[0], { header: this.header, delimiter: ',' })
.pipe().subscribe((result: Array<any>) => {
console.log('Result', result);
this.csvRecords = result;
}, (error: NgxCSVParserError) => {
console.log('Error', error);
});
}
}npm i- Run
ng servefor a dev server and running the demo app. Navigate tohttp://localhost:4200/. The app will automatically reload if you change any of the source files. - Sample CSV File will be provided in the example folder.
